injunction

A term of dual meaning, having reference to a suit to enjoin or to the writ, process, or restraining order issued pursuant to an order or decree obtained in the suit. 28 Am J Rev ed Inj § 2. In the former aspect, a form of action in equity which is designed to protect a plaintiff from irreparable injury to his property or other rights of which a court of equity will take cognizance, by prohibiting or commanding the doing of certain acts. Ladner v Siegel, 298 Pa 487, 148 A 699, 68 ALR 1172. In the latter aspect, a formal command of the court couched in the form of an order, writ, or process, as the local practice may require, directing the persons named therein to refrain from doing certain specified acts which appear to be against equity or conscience, or, where the relief is mandatory in form, commanding them to take certain steps to undo the wrong or injury with which they are charged–a command to refrain from, or to do a particular act. 28 Am J Rev ed Inj § 2. In the legal usage of the term in some jurisdictions, reference to an "injunction" is to what is known in other jurisdictions as a temporary injunction. In such jurisdictions, an injunction in the sense of a final order which determines a controversy is deemed essentially the same as any other judgment or decree in equity, notwithstanding the order may include the enjoining of the performance of an act or an order requiring the performance of an act. See common injunction; irreparable injury; mandatory injunction; preliminary injunction; prohibitory injunction; restraining order; special injunction; temporary injunction.
